Butterflies

29 species of butterfly have been recorded at Treborth ie ,< 7% of the variety displayed by moths. They are as follows:

Small Skipper - first recorded in 2003 and common in some years in the parkland and grassland areas

Large Skipper – common most years in grassy areas and sometimes in woodland glades

Dingy Skipper – rather scarce – not recorded every year – grassy areas

Clouded Yellow – scarce – subject to irregular influx but never reported in more than ones or twos and many years goes unrecorded.

Brimstone – a handful of records, not likely to have bred

Large White - common

Small White – quite common

Green-veined White – common

Orange Tip – quite common

Purple Hairstreak – observed most years in July at edge of woodland; certainly breeds and population at Treborth could be quite large but many individuals frequent upper canopy of oaks so difficult to assess.

White-letter Hairstreak – probably declined but thought to be still present on remaining elms – requires concerted census in July

Small Copper – quite common in grassy areas

Common Blue – common in grassy areas

Holly Blue – quite common along woodland edge and in parkland

Red Admiral – common most years

Painted Lady – very variable numbers according to national influxes

Small Tortoiseshell – has experienced a decline in recent years but still quite common

Comma – has increased over last 40 years and now reasonably common

Small Pearl-bordered Fritillary – has declined in last 40 years and now very scarce
